People always want their vehicles to operate correctly, so they invest in high-quality engine parts. The oil filter is one of these vital automotive components. As a result, driving a car with a clogged oil filter might be hazardous. Some powerful engines, such as Duramax diesel, require the most extensive oil maintenance. Even if you’ve had your Duramax diesel engine for such a long time, selecting the right oil filter for it can be difficult.
This post will have many helpful answers to All Questions About Best Oil Filter For Duramax Diesel Engines.
Oil Filter For Duramax Diesel Engines Buying Guide
Following our evaluation of the best oil filter alternatives, there are a few things to consider.
Pros and Cons of Each Duramax Engine
Before we can conclude which Duramax oil engine is the best, we need to discuss the different pros and cons of each engine. Every type of Duramax engine has its strengths and at least one weakness. Some engines are more popular than others. For example, the pre-emission Duramax engines produced between 2001 and 2007 are highly sought after for their high reliability. On the other hand, more modern engines get more horsepower, torque, and upgradability with Duramax performance parts.
LB7: 2001 – 2004
What is the best Duramax tool?
It is the original Duramax engine that came out in 2001. It is still very popular in the used market. Aside from the LB7 engines sold in California, these engines do not include any emissions control devices. This lack of extra-emission components makes the engine highly reliable. Modern Duramax engines often have problems with emission devices, which often don’t last very long. The LB7’s block is solid rock, and so are most of the internals. One weakness of the LB7 is cracked or leaking injectors.
In most cases, this problem requires injector replacement. The pros are that modern Duramax diesel parts can easily solve most old problems with the LB7. If you’re looking at a part right now, chances are good that any weak or damaged parts have already been replaced.
LARGE: 2004,5 - 2006
As one of the Duramax engines with the shortest lifespan, the LLY is very similar to the LB7 in construction. Its components lack emission control. Except for the model in the L5P, the LLY can get the most additional horsepower from tuning alone of any Duramax engine. As for the weak point, LLY swapped injector problems for overheating issues related to heavy and blown head gaskets. The good news is that head washers are easy and cheap to fix compared to poor injectors.
LBZ: 2006 – 2007
If LLY’s run is short, then LBZ’s run is even faster. Still lacking in emission controls, the LBZ is also one of the most popular Duramax engines. It has the best potential in performance and additional horsepower through mods and tuning of various Duramax parts. The LBZ is reliable and powerful because stronger and more durable than previous engines. The only downside is that the pistons can crack if you get over 600 hp.
However, this is usually not a problem for most owners as it takes around $20,000 in mod money to get to that level and is unnecessary for most apps.
LMM: 2007,5 – 2010
It includes a diesel particulate filter (DPF). It is an oxidation catalyst and a new EGR. Entering the Duramax emission era, the LMM is almost identical to the LBZ, except it has some new emission control devices. All three of these parts are considered to be the failure point of this engine. Fuel economy is also lower in this engine because the exhaust gas treatment process uses fuel to operate. This engine is the same as the LBZ and has plenty of power and reliability.
What is the best Duramax tool?
The LML Duramax takes a leap in performance over the previous engine to produce nearly 400 horsepower and 765 pound-feet of torque. The block, rod, piston, and main bearing were all strengthened to accommodate this large increase in capacity. The front engine’s high-pressure fuel pump has been removed to help control emissions in this engine. Smaller pumps limit the power gain from adjustable or screwed mods.
However, LML has much power out of the box, so most owners may not need power-up mods. Overall, this motor is good to tow and offers good reliability. The main problem is the limited regulatory potential.
L5P: 2017 to present
The L5P is the latest generation of Duramax that debuted in 2017. It’s upgraded from the previous model with 445 horsepower and 910 pound-feet of torque. The biggest change to the L5P Duramax is the addition of die-cast aluminum tips that allow for more airflow. A major improvement to the L5P is the addition of a lift pump. This new unit reduces stress on the main HPFP, helping with horsepower and fuel system reliability.
L5P is still relatively new, but all signs indicate good tuning and modification potential. Overall reliability looks good on paper, but the L5P hasn’t been on the road long enough to hit the big miles and prove its longevity.
Hopefully, at the end of this article, you’ll understand All Questions About Best Oil Filter For Duramax Diesel Engines. The Fram Ultra Synthetic Oil Filter accomplishes what it’s supposed to do and does it effectively. This filter has the added benefit of lasting up to 20k miles before needing to be replaced. You don’t need to change this oil filter very often unless you drive many miles in a short period.
